Background technology
In traditional mechanical cold-formed field, pressing equipment is widely adopted.The pressing equipment of countries in the world is divided into three major types at present:
(1) NC turret punch machine (swiveling head) accounts for total amount 3/1000ths.Because cost is more expensive, use maintenance difficulty bigger, so be difficult to promote the use of.
(2) hydraulic press accounts for one of total amount percentage.Hydraulic press is because process velocity is low, and per minute operates in 10-20 time, so generally be suitable as the use of technology such as stretching.
(3) punching machine accounts for total amount more than percent 95.Punching machine is because process velocity is fast, and per minute can 20 times to 150 times (high-speed high-performance exception), so can be widely-used in the punching press industry.
Punching machine is divided into two big classes: 1. positive clutch and 2. friction clutch.Positive clutch is widely used in developing country, and friction clutch is widely used in developed country.Shortcomings such as rigid clutch pressing machine has that noise is big, poor safety performance, energy consumption are big.Friction clutch forcing press noise and security performance are better than positive clutch, and energy consumption is a little more than positive clutch, but cost is one times of positive clutch, and lathe weight is greater than positive clutch (also calculating with 63T), and various parts standard spares are more than positive clutch.
The NC turret punch machine cost is more expensive, and punching machine has above-mentioned shortcoming.The advantage of hydraulic press has many, how to solve low this defective of hydraulic press process velocity, is a problem that is worth research.
All exist a common problem for above-mentioned three class pressing equipments, that be exactly when needed power is with punching press in the stroke way energy needed as many so cause the huge waste of the energy.
